Filter properties

Here, you can edit and test your filters. Filters define which files (or folders) shall be synchronized.

You can test your filter settings, with custom strings (manual mode) or based on current task directories, and files (task based). In manual mode, the filter evaluate every line of text in Query field.

TIPP: if you selected Extension, or Equals simple filters, you can drag and drop files to Definition field. New extensions or filenames added (ver 0.63)

The filter properties implement two type of filters:

  • Simple (extension, equal, contain) filter
  • Regexp based (case sensitive/insensitive) filter

Simple filters:

Easy to use simple filtering. Evaluation is based on filter definition field value. All simple filters are case insensitive, and you can add multiple values, separated with semicolon (Example: a;b; c;). If definition field value is empty, the filter is disabled (all files/folders accepted).


Case insensitive extension-based file filtering. You can define multiple extensions. Special extension separator chars (. and *) accepted, but not required.


Filter definition: .dAt; *.sav; exe

Matches: example.DaT; Example.sav

Doesn’t match:; example.exe.bak


Case insensitive string equalisation.


Filter definition: apple.dat; apple.sav

Matches: Apple.dat; Apple.sav

Doesn’t match: Apple1.dat;


Case insensitive strings contained.


Filter definition: apple; peach

Matches: Apple.dat; Yellow.Peach.sav

Doesn’t match: Aple1.dat;


 Advanced RegExp filters

These filters are based on Java regular expressions. You can find a detailed guide about the “RegExp” explanations used by the filter here.  The evaluation uses include and exclude fields.

The include/exclude evaluation sequence is:

validate include regexp

if include regexp definition is empty -> accept file/dir

if include regexp isn’t empty, evaluate include regexp

if not match -> not accept file/dir

if match

validate exclude regexp

if exclude regexp definition is empty -> accept file/dir

if exclude regexp definition isn’t empty, evaluate exclude regexp

if match -> not accept file/dir

if not match -> accept file/dir



  • Include regexp: ^.*\.exe
  • Exclude regexp: alma

Input: peach.exe

Result: true

Input alma.exe

Result: false
